Williams scored twice to give the Kings a two-goal lead in the second period and an awesome comfort level for Kings goaltender Jonathan Quick.

The Kings hung on with those Williams goals for their defending Stanley Cup champion lives as they knocked off the Sharks 2-1.

Williams has a knack for the big games, and his goals – and Quick’s stout goaltending -put the Kings in the Western Conference Finals for the second consecutive year.

The Sharks scored in the third period on a Dan Boyle goal at 5:26 in the third period, but the Kings held on with Quick making spectacular saves.

But Williams gave the biggest save of all with those early goals for a 2-0 lead.

Williams has scored five goals and four assists in four Game 7s. That’s nine points in Game 7s.

“I think I could’ve had three or four goals. I had plenty of opportunities,” Williams said. “It’s funny how the puck comes to you a little more often sometimes in different games. It was nice to get two, but it would’ve been nice to get a little more comfort.”

Williams provided the early comfort, and Quick provided it late.

And somehow, the anxiety and pressure of Game 7 is none of that and all comfort for Williams.

“Hopefully, he does it again if we have to do another one,” defenseman Rob Scuderi said.

One more goal and Williams would’ve been the first Kings player since Wayne Gretzky to have a hat trick in a Game 7.

Williams was the biggest star in the house Tuesday, even with Tom Cruise, David Beckham and Justin Bieber attending. And Kobe Bryant had an inspirational message for fans on the video board, but Williams was the man of the hour.

It was Game 7, after all.

Justin “Mr.Game 7” Williams has a nice ring to it, eh?

“I’m going to have to play a few more Game 7s and have a little more success to get that nickname,” Williams said. “I’m certainly happy I was able to contirbute. Goals have been tough to come by for me in this series.”

And if he was to get caught up in his Game 7 statistics, teammate Dustin Brown provided some levity.

“The last Game 7 we had to play, he had to score an empty-netter, so I don’t want to give him too much credit,” Brown said with a laugh.

The Kings live on drama this season, and Williams tried to take it away. The Kings didn’t score in the first period, but neither did the Sharks.

Williams came to the rescue with goals at 4:11 on the power play – he stuffed the puck in the corner against Antti Niemi – and at 7:08 on nifty passes from Anze Kopitar and Slava Voynov. That gave the Kings a 2-0 lead and all the comfort they’d need.

That this crucial elimination game was at Staples Center was huge. The home team won every game this series.
